Can't see my RAID 5 Array in Win 10

Maybe you need that to initialize the volume.

This appears to be the problem, and the initialization process needs to be performed in the Intel RTS software. I've started that process, but it looks like it's going to take awhile. According to one random guy on the Internet his drives initialized at about 200 GB per hour. Hopefully this one will go a little faster because 14.9 TB / 200 GB per hour is 74.5 hours. That would be sometime Thursday morning before the process is complete. Initialization was already at 1% about 20 minutes into the process though so maybe these drives will go a little faster.
